Here is a great video from d3way that goes over all the details of the upcommong vortex FPV racing miniquad frame from ImmersionRC. So if you are considering this quad frame this 40min video tells you all you need to know about this frame to allow you to male an informed decision

For some reason the video above has been made private, so untill it is fixed here are a few other videos for you to look at:

The first video is from Tested, who talked to an immersionRC representative over in the USA

And here is an onboard video from Boris B. flying one of the early versions of the Vortex FPV Quadcopter showing how much speed and performance this miniquad packs.
